I have a Toshiba Satellite P755 S5182. It works/fails almost identically to the posters above (on kubuntu 12.04). One of the major reasons I selected this notebook was for the backlit keyboard (which works fine on Windows 7 - which I use only when forced to, but not on Linux.)
The main differences I see are 1) no files with illumination" in their names, 2) Fn+Z does not display anything, but the key does have a backlight icon on it. The toshiba_acpi module is loaded, but lsmod says it's used by none. The source code for it on my machine appears to be very old (2010) 386 code and a cursory scan of it did not show me anything that looked like it had to do with the keyboard backlight, but I'm not much of a C coder these days and I could easily have missed something. If there is any code to test to diagnose or fix this problem, I'd be happy to help. I really need this feature. I'm not ready to upgrade to a new distro release any time soon, but I have spare partitions where I can install another (newer) distro for testing purposes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169386 Title: [keymap] Toshiba satellite A660: backlight key does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1169386/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
